What It Is

Dumb Stock API is a minimalist stock ticker API for developers. It does not provide quotes, financial metrics, or historical prices; instead, it reads and organizes publicly released securities list files from multiple exchanges and exposes them in JSON, CSV, or tickers-only formats. Data is synced several times a day and covers multiple exchanges, including NYSE, NASDAQ, AMEX, JPX, TSX, SZSE, and TWSE.

Core Capabilities

Its main use case is retrieving basic reference data such as ticker symbols, security names, ETF status, and listing exchanges. Queries are straightforward: you can filter by countries or exchanges, and parameters such as is_etf, name_search, and ticker_search are also supported. Output formats include json, csv, and tickers-only. It also provides direct CSV links for popular exchanges, making it suitable for scripts, data imports, and search box autocomplete.

Pricing and Requirements

The website clearly states that personal use is free. If users make money through the stock API or use it as a company, they are expected to “money me,” but no specific pricing, plans, payment methods, or contract terms are published. The technical barrier to entry is very low: it is essentially a standard HTTP API. The documentation includes example URLs, response field descriptions, and a list of supported exchanges, but no SDK is provided.

Pros and Cons

Its strengths are simplicity and clarity: the calling method is easy to understand without complex authentication, and JSON/CSV are friendly to both developers and spreadsheet tools. The drawbacks are also clear: the available fields are very limited; is_etf may be null when no source information is available; English names for some Asian exchanges may be empty; rate limiting is described only as “reasonable,” with no defined threshold; and there is no visible SLA, versioning policy, open-source statement, self-hosting option, or enterprise support information.

Who It’s For

It is suitable for lightweight use cases such as personal projects, prototypes, internal data initialization, and stock search autocomplete where a quick securities ticker list is needed. It is not suitable for production-grade financial systems that require high availability, strong compliance, real-time market data, deep financial datasets, or explicit commercial contracts.

Access from China

The collected text does not provide information about access from mainland China, ICP filing, CDN usage, or payment options, so its accessibility from China can only be considered unknown. If using it in a production environment in China, test network connectivity and stability first. For critical business use, consider preparing alternative data sources such as official exchange files, Alpha Vantage, Financial Modeling Prep, Polygon.io, and Twelve Data.
